sealants are plastic coatings that are usually placed on the chewing
(occlusal) surface of the permanent back teeth —the molars and sometimes
premolars—to help protect them from decay.
chewing surfaces of the molar and premolar teeth have grooves,
"fissures" that make them vulnerable to decay. These fissures can be
deep, are difficult to clean, and can be narrower than even a single
bristle of a toothbrush.
accumulates in these areas, and the acid from bacteria in the plaque
attacks the enamel and cavities can develop. Fluoride helps prevent
decay and helps protect all the surfaces of the teeth, dental sealants
provide extra protection for the grooved and pitted areas by providing a
smooth surface covering over the fissured area.
first dental sealant to be placed is usually on the fissure of the
first permanent molar tooth, once the chewing surface of the tooth has
erupted completely beyond the gum.
the chewing (occlusal) surfaces of these teeth are sealed, the dental
sealant will help protect the tooth except for the wisdom teeth which
come through much later. Molars and premolars continue to erupt until
eleven-thirteen years of age and the chewing surfaces of these teeth can
be sealed after they have erupted beyond the gum.
sealants have been around and proven to work since the 1970's. Dental
sealants can last many years, but if needed can be replaced quite
At Elison Dental Center,
we recommend that all children receive dental sealants once their
permanent teeth have started to erupt. Save
